After a good deal of reflection and consultation with my family, I have decided that (aside from pre-existing commitments, of which I have a few) I will no longer give lectures or participate in conferences, whether in person or via video link. I have a great deal that I want to think about and write about, and a dwindling supply of time in which to pursue the tasks I care about most. I understand that this decision might limit sales of my books, and make me even more isolated and ignored than I am already. That’s a trade-off that I simply must make. I feel sure that this is the right thing to do; indeed, the necessary thing to do. I hope that the work I produce in the future will bear out that judgment.
